WR-G305i Wideband Scanning Receiver
_________________________________________________________
Introducing a breakthrough
Convert your desktop PC into a most sophisticated radio monitoring
station! The WiNRADiO
WR-G305i is a software-defined PC-based
wideband scanning receiver covering a frequency range from 9 kHz
to 1800 MHz (expandable to 3500 MHz with an optional
downconverter).
The receiver comes on a standard two-third length PCI card and is
compatible with all modern desktop computers with an available PCI
2.2 standard slot.
Features
Frequency range from 9 kHz to 1800 MHz
(except cellular bands where required by law)
Software-defined demodulation
Extraordinary sensitivity
Tracking front-end filters
Excellent strong signal handling
Real-time spectrum analyzer
Spot-on tuning in 1Hz steps
Accurate signal strength indicator
Fast scanning speed
Multiple squelch modes
Very low phase noise
DRM decoder option
APCO P25 decoder option
3.5 GHz downconverter option
Standard PCI interface
With the Professional Demodulator Option , the many additional
features include:
Continuously variable IF bandwidth 100 Hz - 15 kHz
User adjustable filter selectivity
WiNRADiO
Digital Bridge™ compatibility
Built-in test and measurement instrumentation
Interactive block diagrams
Plug and Play installation
The WR-G305i is the first of our G3 Series of VHF/UHF software-
defined receivers.
The "G3" stands for "the third generation": As the original, award-
winning, first-generation WiNRADiO
WR-1000i receiver was the
world's first commercially available wide-band receiver on a PC card
when launched over a decade ago, the newly introduced WR-G305i
is the world's first commercially available software-defined
VHF/UHF receiver on a PCI bus card.
A Software Defined Radio (SDR) is such where demodulation and
last IF (intermediate frequency) processing are done entirely in
software. Usually this means using a DSP, but in the case of the
G305i, this processing is done on a personal computer using a
sound card (most modern PCs are now faster and more powerful
than many DSPs were only a few years ago). So, if you own a PC,
the chances are that you already own an important part of a
software defined radio receiver!
In addition to the flexible and friendly user interface , with its
numerous functions and facilities not normally available on any
conventional receiver, the
WiNRADiO G305i receiver excells
particularly by the ability of its demodulators.
While the Standard Demodulator provides performance of a highly
respectable scanning receiver including synchronous AM
demodulation and a real-time spectrum scope, the optional
Professional Demodulator offers even more: continuous IF filter
bandwidth adjustment (in 1Hz increments), interactive block
diagrams with two additional audio spectrum scopes, and even
inbuilt THD and SINAD measurement facilities.
An optional DRM decoder/demodulator is also available.
The WiNRADiO G305i : A ground-breaking general-coverage
receiver that opens many new possibilities in the world of both
conventional and digital communications. Prepare to be amazed!
